When I read the first original TNG novel I felt the characters were a little out of sync with what was depicted on screen; as if the author had the series bible but hadn’t seen any episodes.
That's exactly the case. Novels take a long time to get done, so the first several novels in each of the TNG through ENT novel lines were written before the shows had premiered or even completed filming, and thus the novelists had to make do with what early material was available -- which in the case of Ghost Ship was just the bible and the pilot script, IIRC. And TNG changed a lot from the initial bible due to all the chaos and turnover on the writing staff.
